The cable news network made a serious boo-boo on Sunday during talking head Shannon Bream's show, posting an on-screen image of Fey — in character as Palin during a 2008 "Saturday Night Live" skit — instead of the possible 2012 presidential candidate herself.

Imitation might be the sincerest form of flattery, but it's doubtful that Palin feels terribly buttered up by the switcheroo.

In a statement released on Monday, Fox's executive producer of weekend programming, David Clark, said., "This past Sunday during 'America's News Headquarters,' a graphics error was made during a segment on former Alaska Governor Sarah Palin. The producer has since been disciplined and an explanation and apology will be made in the same hour next Sunday. Fox News regrets the error."
